The engines.

Powering the 911 GT3 models is a
water-cooled six-cylinder Boxer
engine with four-valve technology
and enhanced VarioCam variable
valve timing (page 36). The vehi-
cle's high-performance concept
produces an impressive maximum
engine speed of 8,500 rpm.
In the 911 GT3, the engine gener-
ates 320 kW (435 hp) from a total
Drive
displacement of 3,797 cm
corresponding to an output of
115 hp per litre. The maximum
torque is 430 Nm at 6,250 rpm.
The 911 GT3 accelerates to
100 km/h (62 mph) in 4.1 seconds
with a maximum speed of
312 km /h (194 mph).
The 3.8 litre engine in the new
911 GT3 RS delivers even more
3 , power: 331 kW (450 hp). The
output is 118 hp per litre. This
increase is due to the two new
double-flow air filter housings and
the new variable intake manifold
with larger intake tubes than those
used on the 911 GT3. The greater
throughput of air increases engine
power. In terms of performance
data, the maximum torque of
430 Nm is reached at 6,750 rpm.
